Information about salaries in Paris

Maybe the ones that live in Paris can help me! :-)As I am planning to go to work there, I would like to know when I see a job announcement, which shows the salary offer (brute), how can I calculate how much is going to be the net salary, lets say if I see that an enterprise offers € 1.600 brute, which is the percentage of deductions I have to discount to know more or less how much is going to be the net salary? I am looking for a job as a receptionist senior in a luxury hotel if that can help. And besides the monthly deductions, at the end of the year, there are also the taxes to pay? Thanks a lot for your attention! This information will be very helpful to me, before answering a job announcement! :-)
